FAN MAINTENANCE & CASE CLEANING
FANS
Reach-in door cases feature electronically commutated
(ECM) fan motor assemblies, whereby the fan blade, fan
motor, and basket are integrated into a single unit.
)
an assemblies may be changed with an easy two-step
process without lifting up the plenum, thereby avoiding the
necessity to unload the entire product display to change
the fan assembly:
Unplug the fan motor (Fig. 1
) from the receptacle on
the exterior of the fan plenum. Push the power cord
back through the plenum opening.
Remove fasteners, then lift out the entire fan basket.
(Reverse procedure when re-installing fan assembly.)
DANGER!
SHOCK HAZARD
Always disconnect power to case when
servicing or cleaning. Failure to do so
may result in serious injury or death.
ATTENTION!
Power cord must be pushed back through
the plenum opening before removing the
fan basket. Failure to do so may result in
damage to the power cord.
CLEANING PROCEDURES
A periodic cleaning schedule should be established to
maintain proper sanitation, insure maximum operating ef-
ficiency, and avoid the corrosive action of food fluids on
metal parts that are left on for long periods of time. We
recommend cleaning once a week.
•
To avoid shock hazard, be sure all electrical power is
turned off before cleaning. In some installations, more
than one disconnect switch may have to be turned off
to completely de-energize the case.
•
All surfaces pitch downward to a deep-drawn drain
trough, funneling liquids and other debris to the waste
outlet. Check waste outlet before starting the cleaning
process to insure it is unclogged. Avoid introducing
water faster than the case drain can carry it away.
•
Lift the fan plenum to gain access to the coil for clean-
ing and maintenance (Fig. 1
).

CAUTION!
Exercise extreme caution when working in
a case with the coil cover removed. The
coil contains many sharp edges that can
cause severe cuts to the hands and arms.

•
To clean the lights, shut off the lights in the case, then
wipe them down with a soft, damp cloth. Avoid using
harsh or abrasive cleaners as they may damage the
lights. Be certain that the lights are completely dry be-
fore re-energizing.
•
If any potentially harmful cleaners are used, be cer-
tain to provide a temporary separator (e.g., cardboard,
plastic wrap, etc.) between those cases that are being
cleaned and those that may still contain product.
•
Avoid spraying cleaning solutions directly on electrical
connections.
•
Allow cases to be turned off long enough to clean any
frost or ice from coil and pans.
•
Remove kickplate and clean underneath the case with
a broom and a long-handled mop. Use warm water
and a disinfecting cleaning solution when cleaning un-
derneath the cases.
